Sulfonation of benzene Guías de estudio, Notas de estudios & Resúmenes

Contains: -The accepted structure of benzene in terms of hybridisation, sigma and pi bonding, and delocalisation of electrons. -Why this evidence also disproves the originally suggested Kekulé structure for benzene, including reference to the bond lengths of C-C, C=C and those within benzene. -Examples of evidence (such as infrared, x-ray and thermochemical analysis) that support the structure of benzene as being very stable and regularly shaped. -The chemical properties of ben...
